This list shows most of the additional respiratory protection requirements that may apply to your workplace. Since it's not a complete list of all rules that address respirator use, you’ll need to check the Find a Rule webpage for other rules that may apply to your industry and activities.

Keep in mind that these requirements are "supplemental" to the requirements specified in the Respirators, Chapter 296-842 WAC. They may, at times, preempt some of the requirements of the Respirators rule, if noted.
